AD7194 24-Bit Sigma-Delta ADC

AD7194 Description

8-Channel, 4.8 kHz, Ultralow Noise, 24-Bit Sigma-Delta ADC with PGA AD7194 .
The AD7194 is a low noise, complete analog front end for high precision measurement applications.

AD7194 Features

* Fast settling filter option 8 differential/16 pseudo differential input channels RMS noise: 11 nV at 4.7 Hz (gain = 128) 15.5 noise-free bits at 2.4 kHz (gain = 128) Up to 22 noise-free bits (gain = 1) Offset drift: ±5 nV/°C Gain drift: ±1 ppm/°C Programmable gain (1 to 128) Output data rate: 4.7 Hz

AD7194 Applications

* It contains a low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The on-chip low noise gain stage means that signals of small amplitude can interface directly to the ADC. The device can be configured to have eight differential inputs or sixteen pseudo differential inputs. The on
